Annotation Type GravitonTarget

@Retention(value=RUNTIME)
 @Target(value=TYPE)
public @interface GravitonTarget

This annotation defines which version of Graviton this app *targets*. Target versioning is a scheme that allows apps to declare what version of a platform they were tested against. This allows that platform to switch on or off behavioural changes that might risk being backwards-incompatible, depending on whether or not the app can tolerate them. By declaring a target version that's greater than 1 (the default), your app can indicate that it's not necessary to engage backwards compatibility logic that may impact performance, usability, security etc.

The best way to use this annotation is to always add it to your main class (the class defined in your manifest as the startup class). Set the version to whatever version of Graviton you tested your app with. Then when you re-test your app on a later version, change this number to match before starting your testing. If it's all OK you know your app is compatible. Changes linked to the target version will be published on the Graviton website.
